Impact of environment including advantages and disadvantages.

Answers

Advantages of Non-Renewable Energy Because non-renewable energies seem abundant, like oil, gas and coal, some experts believe if channeled correctly, our supplies will be safe for future generations. Non-renewable energy sources include oil and petroleum products, gasoline, diesel fuel, and propane, natural gas, coal, and uranium used for nuclear energy. Some environmentalists include our forests, trees, and plant life as a non-renewable energy source as well especially due to the deforestation of our forests.One advantage of non-renewable energies is that right now, they seem widely available and affordable. Oil and diesel are still good choices for powering vehicles. They are cost effective and much easier to produce and use. Non-renewable energy also has market value where a supplier or manufacturer makes money and pays workers enhancing economies.Although governments struggle with fair trade practices, many countries have a non-renewable energy source which can used as a bargaining tool to help their economy stay afloat.Disadvantages of Non-Renewable Energy On the other side, there are many disadvantages to non-renewable energy. Because non-renewable energies come from sources on our planet, once they are gone they can't be replaced or revitalized.Pollution grows greater through the by-products they leave behind and mining of non-renewable energy is causing damage to our environment. There is no doubt that fossil fuels contribute to global warming and to break humans of their habit to lean on non-renewable energy sources remains a challenge.The Advantages, Disadvantages and Environmental Impacts of Renewable Energy SourcesEnergy TypeAdvantagesDisadvantagesEnvironmental ImpactsGeothermalUses energy generated within the Earth’s core.The heat can be used to heat houses or as steam to turn turbines and create electricity.There are 2 ways of getting this type of power.There are several places in the U.K. where the hot aquifer scheme could be used.It requires the input of water going into the aquifer from above.It requires a borehole for the extraction of hot water or steam.Large negative visual impact.High noise pollution.Could cause seismic activity from explosions created to fracture aquifer to a greater extent.Destruction of habitats where pumping stations and boreholes are made.Possible radioactive leaks.HEP3 types:Micro-HEPPump storageLarge scale damEnvironmental AdvantagesAllows for leisure and water recreational facilities.Prevent mass flooding.Reservoirs allow nearby farmers to create irrigation system to grow crops on less fertile land and soil all year round.Don’t contribute to global warming, Acid rain.No emissions of CO2 and Sulpher dioxide. No risk of radioactivity.Environmental DisadvantagesFlooding of the land causes existing owners to relocate themselves.Greater chance of earthquakes caused by the weight of the dam on the earth’s crust.Less sediment below the dam means less energy is used by the river to transport it, giving the river greater eroding power.Flooding destroys habitats and Ecosystems also during dam construction.High temps allow Microorganisms to grow whichIncreases the O2 demand causing existing wildlife to be starved of O2.Dams can prevent fish migration patterns upstream to spawn.Decaying plants at the bottom of the reservoir sub merged by flooding release green house gases.Large Dams can cause localized microclimates.Soils downstream don’t get nutrients because fertile silt is deposited upstream.Solar energy3 types:Passive (heating of buildings by sunlight-saves electricity),Photo-voltaic(generating electricity from light)Photo-thermal(heating water from sunlight-saving electricity)PassiveClean energy from insolationReduces electricity consumptionPhoto-voltaicNo emissionsNo noise pollutionSilica, the substance used to produce photovoltaic cells, is highly abundant in Earth’s crust.Can provide energy in remote locationsPhoto-thermalReduces electricity consumptionPhoto-voltaic:UnreliableOnly effective in sunny climatesNegative visual impact, although this is minimal. Photovoltaic cells now being developed to act as roof tiles.Does not produce huge amounts of electricity.Photo-voltaic:Waste produced during the manufacture of photovoltaic cells is toxicWind PowerNo emissionsReduces dependence on fossil fuelsLand use does not conflict with present farming operations (land can still be grazed etc.)Negative visual impactNoise pollutionUnreliable due to changeable wind patterns. Turbines can only work between a small range of wind speeds.Unsafe in strong winds, as the propellers can break. Also flying ice can be a problemOnly efficient in certain areasCan cause an obstruction to birds
